Are they "needed?" No. Will they give you an increase in power? That all depends on the roller rockers as, like with most everything else, they are not all created equal. I can vouch for the Crane Gold Quick-Lift roller rockers that they do provide increased power.

I'm new to this game, but I was under the impression that, given quality components and a professionally done install, a full roller set-up made more power due to less friction. No?
Also, just from reading between the lines, it seems as though more than a few people aren't convinced that aftermarket components, especially valvetrain components, are any better than OEM.
I always thought that because aftermarket component manufacturers had the luxury of sitting back and scrutinizing the weak points of OEM components, and because OEM components are made in such vastly larger numbers, the aftermarket stuff couldn't help but be better....at least the aftermarket stuff with a solid, long-term good reputation.

LS1 already have rollers from the factory. The weak point is the bearings. Get yours redone by Harlan through nasty perf.----->

If you told someone you were selling them a set of "roller rockers" and sent them a set of OEM LS1 rockers, I think the buyer would be more than a little disappointed.

I gained 10 rwhp and 8 rwtq over my best with the SLP 1.85 OEM-type rockers with the Crane 1.80 Quick-Lift ones. Yeah, I'm a believer.

10 RWHP just from going with roller-rockers? The only advantage to roller-rockers is a reduction in friction, part of your gains must have come from the increased ratio also.

The beauty of the Crane Quick-Lift rockers is that they have a variable ratio. They start off the valve seat with a ratio of 1.92. This drops to the advertised ratio of 1.80 (actually 1.82) at .200-.300" of valve lift and maintaiins this ratio until the valve starts to close and again reaches the .200-.300" of lift range. The ratio then increases again to 1.92 where it stays until the valve is seated. These roller rockers not only increase peak hp, but they increase power across the entire rpm range.
